Parameter definitions
6.1
Common mode rejection ratio (CMR)
The common-mode rejection ratio (CMR) measures the ability of the current-sensing
amplifier to reject any DC voltage applied on both inputs Vp and Vm. The CMR is referred
back to the input so that its effect can be compared with the applied differential signal. The
CMR is defined by the formula:
6.2
Supply voltage rejection ratio (SVR)
The supply-voltage rejection ratio (SVR) measures the ability of the current-sensing
amplifier to reject any variation of the supply voltage VCC. The SVR is referred back to the
input so that its effect can be compared with the applied differential signal. The SVR is
defined by the formula:
6.3
Gain (Av) and input offset voltage (Vos)
The input offset voltage is defined as the intersection between the linear regression of the
Vout vs. the Vsense curve with the X-axis. If Vout1 is the output voltage with Vsense = Vsense1 = 50
mV, and Vout2 is the output voltage with Vsense = Vsense2 = 5 mV, then Vos can be calculated
with the following formula.
6.4
Output voltage drift versus temperature
The output voltage drift versus temperature is defined as the maximum variation of Vout with
respect to its value at 25 °C, over the temperature range. It is calculated as follows:
with Tmin < Tamb < Tmax.
